Plastics Testing: Increasing Laboratory Efficiency & Throughput

  2. 2. TYPES OF SETUPS IDEALTYPICAL • Pneumatic grips with alignment aids • Integrated micrometer • AutoX750 extensometer • Manual wedge grips • Micrometer + calculator • Clip-on extensometer
  3. 3. THE CYCLE TIME FORMULA Fixed Times Variable with different setups DIMENSIONAL MEASUREMENT SPECIMEN REMOVAL EXTENSOMETER ATTACHMENT TESTTIME EXTENSOMETER REMOVAL SPECIMEN INSERTION + CYCLE TIME Integrated vs. Manual Automatic vs. Manual Time to Install Correctly & Grip Closing Automatic vs. Manual Grip Opening =
  4. 4. THE DIFFERENCES DIMENSIONAL MEASUREMENT SPECIMEN INSERTION/ REMOVAL EXTENSOMETER ATTACHMENT/ REMOVAL • 6 measurements/specimen • ~42 keystrokes/specimen 10 TESTS = 420 KEY STROKES • Time spent aligning by eye • Grip closing time is longer INCREASED USER INTERACTION • Time spent aligning by eye • Time to pause test to remove • 6 measurements/specimen • ~7 keystrokes/specimen 10 TESTS = 70 KEY STROKES • Specimen inserted quickly and easily with alignment devices • Grips close quickly • Attaches aligned every test • Automatically removes without pausing MINIMIZED USER INTERACTION

  7. 7. EFFICIENCY IN SOFTWARE MODIFICATIONS Multiple Users Some changes can be made quickly and easily to existing Bluehill® test methods to • Decrease individual test time • Minimize downtime between tests • Allow for extra time spent on more value-added tasks Multiple Materials Multiple Inputs CAN COST $£€
  8. 8. CHOICE INPUTS • Consistent entries • Fewer spelling mistakes and incorrect inputs • Easier to sort data post-test • Fewer corrections • Saves time
  9. 9. PROMPTED METHODS • Optimal for a multiple-operator environment • Consistent entries • Consistent test flow from operator to operator • Customizable for different tests • Prompt before sample, before specimen, after specimen, after sample, etc.
  10. 10. OTHERS… Preconfigured Test Methods Bluehill Application Modules come with a variety of pre-made test methods to quickly get you off the ground. E.g. Plastics Module:ASTM D638, ASTM D790, ISO 527-2, 3, ISO 178, ISO 604, and others One Click Testing An AutomaticAir Control Kit (footswitch with 2 pedals) communicates with the frame and software to allow you to automatically begin a test when the pneumatic grips close. Audio Prompts Play a wave file at different moments throughout the test to notify the operator that an action has taken place (e.g. remove extensometer, test ended).
